I noticed that the front tires are worn in the outer edges (please the pic). The rear tires are fine (another pic). The tires are OEM Michelin 18''

Questions:
- is it normal wear at 23k miles? In my previous BMW tires were worn faster on the rear axle and rather in the inner edge.
- do you think the alignment should be checked?
- should I rotate them or it is too late?

This is a common problem (I am sure ARD will chime in) with BMW's. These 5-6k pounds trucks are meant to handle like a 3k car. To accomplish this the camber on these cars are set up just for just that, handling. To achieve that, you compromise tire wear due to the aggressive but within spec settings. You can have a competent shop dial that back closer to zero (which will be out of BMW performance spec but still fine) and achieve a more consistent longer tire wear. But you may loose some of the driving performance. Some people won't even care or notice the difference, others may not like the loss of performance. That will be up to you to make that decision.

Personally, almost 30k on a set of BMW tires is good in my book but I am also jaded considering I have only owned V8 BMW's and the cars I drive usually eat tires up rather quickly.

As ARD knows, I was having some issues with my X5 (2009 which I recently purchased) drifting, etc. Replaced
some worn bushings, etc. in the front end (made a big difference in handling) and then had an alignment done last week when I had my snows put on. Unbelievable difference. I'm sure I'll have better tire wear now ...

No. Check the alignment. Rotating won't help... well, swapping front/rear will add some mileage, but won't fix the problem. Do you corner hard? No necessarily @ high speed, but say there's a sharp turn with incline that you take daily? As funny as it sounds, it could be the reason.

Is the toe 0.01-0.03 the only value I should asked them to set? Is it still in the BMW spec? If not, can they refuse to set it?

Thanks

The BMW spec (by memory) is 0.00 to 0.08 each side. So asking for 0.02 on each IS still IN spec. But dealerships can be lazy, if they toss it on the rack and the numbers are 'green' (ie in the spec) they USUALLY will not change them. Just have them write your wishes IN THE REPAIR ORDER. Just make it clear you have specific needs in advance and they should accomodate,

On the other numbers, they should just be in spec. I like Camber in the middle of the range AND even from side to side.

My bad smyles. I have read so many tire wear threads problems for some reason I was thinking inside and not outside like the OP posted My response was not a theory but is a fact on for tire wear on BMW's. I have gone through many sets of tires on the last 8 BMW's with inside wear so my theory is pretty solid.

why 0.05? you wrote (from memory) that the BMW spec is 0.00 and I should demand toe between 0.01 to 0.03 (i.e. something around 0.02 above the minimum spec). They told me the BMW spec is 0.03-0.13. therefore I thought that 0.05 would be OK since it is 0.02 above the minimum

This is not BMW computer - should I be worried whether the spec are wrong? I think they are using hunter alignment system, if it means anything

is setting alignment out of spec (to minimize the wear) something common?

unfortunately I do not follow the rest about rear toe spec, cross toe, etc.
